Acridine-1,2,4-triazole-5-thioketone compound and preparation method and applications of acridine-1,2,4-triazole-5-thioketone compound

The invention discloses an acridine-1,2,4-triazole-5-thioketone compound and a preparation method and applications of the acridine-1,2,4-triazole-5-thioketone compound. The preparation method of the compound comprises the following steps: 1) by taking an o-bromobenzoic acid and p-methoxyaniline as raw materials, taking potassium carbonate and copper powder as catalysts, and taking isopentyl alcohol or n-amyl alcohol as a solvent, reacting so as to obtain a compound 1; 2) carrying out cyclization on the compound 1 by using phosphorus oxychloride so as to obtain a compound 2; 3) after the compound 2 is dissolved by using an organic solvent, in the presence of tetrabutylammonium bromide, reacting the dissolved compound 2 with sodium sulfocyanate so as to obtain a compound 3; 4) after the compound 3 is dissolved by using an organic solvent, reacting the dissolved compound 3 with m-nitrobenzoylhydrazine so as to obtain a compound 4; and 5) reacting the compound 4 with sodium carbonate, carrying out suction filtration on a reactant, collecting filter liquor, adjusting the pH value of the filter liquor to be less than 4, separating out precipitates, and carrying out suction filtration on the precipitates. In-vitro antitumor test results show that the compound has a significant in-vitro antitumor activity to tested MGC80-3, NCI-H460 and T24.
